SMPS are different ... They don't need caps as badly as linear or unregulated supplies, and they even have a limit to what capacitance they can drive.

Before adding any caps, do check out what maximum capacitance the supply can handle on its output.

And when you're adding caps you want to add them as close as the load as possible, that means connecting the leads to the amp board, not the PSU.
